In windows, you could navigate tree menus with left/right keys, now in ubuntu 11.04 (and perhaps previous versions?) i have to hold the shift key while i do that, its quite annoying, any way to configure this?

Edit:I've attached a picture indicating the problem:

So in windows, with the focus on the circled element, I could tap the "right key" and it would open up this folder. In ubuntu, in eclipse, nautilus, etc, i have to hold down shift and the right key to get the same behaviour.

@jo-erlend he's asking if the windows folder tree navigation thing can be done here - in Tree View, you can expand/collapse the tree by using the right or left keys respectively. He wants that functionality in Ubuntu... but i dont think you can :P
